Is this with the Cutoff Pedal parameter turned all the way up?

The Yamaha pedal has a different resistance and pinout compared to the Polaris pedal. The Polaris uses a variable 0-100K resistor between sleeve and tip. The Yamaha is really a volume pedal with tip, ring and sleeve, and has a lower resistance, so it's not compatible.
